Description

Technical Field

[0001] This invention relates to the field of energy-saving building material production technology, specifically to a demolding device for concrete preparation. Background Technology

[0002] In the production and preparation of concrete components (especially energy-saving concrete components, such as lightweight thermal insulation concrete components and foamed energy-saving concrete components) in energy-saving building material systems, demolding is one of the key processes. Its core is to separate the molded energy-saving concrete workpiece from the steel mold while ensuring the workpiece remains intact and undamaged, and simultaneously ensuring the mold can be reused. This guarantees the production quality and efficiency of energy-saving building materials and reduces the production cost of energy-saving components. Currently, the demolding operations for existing energy-saving concrete components are mainly divided into manual demolding and simple mechanical demolding. However, these methods still have some shortcomings in practical use: manual demolding relies on operators to separate the concrete workpiece from the mold by prying or knocking. This is not only labor-intensive and inefficient, but also difficult to control the force of manual knocking, which can easily lead to damage such as chipped corners and cracks on the surface of the concrete workpiece, affecting product quality. In addition, during manual operation, operators need to be in close contact with the mold and concrete workpiece, posing safety hazards such as being bumped by the mold and scratched by flying concrete debris. Mechanical demolding devices mostly use a single clamping and ejection method for demolding. Their structure is simple, their function is limited, and their demolding effect is poor. The single clamping and ejection method relies solely on the difference in gravity between the mold and the concrete workpiece to achieve separation and the mechanical ejection force to achieve demolding. When the concrete workpiece is tightly adhered to the mold, it is very easy to cause damage to the concrete workpiece by the ejection. Moreover, after demolding, the concrete workpiece falls directly, which can easily cause collision damage. Summary of the Invention

[0003] The purpose of this invention is to provide a demolding device for concrete preparation, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a demolding device for concrete preparation, comprising a base, a first motor fixed on the base, a conveying roller fixed at the output end of the first motor, the conveying rollers being connected to the base by equally spaced bearings, and adjacent conveying rollers being synchronously rotated via pulleys and belts; a lifting mechanism installed on the base, which is used for supporting and adjusting the mold; a support rod fixed on the base, a top plate fixed at the upper end of the support rod, a driving mechanism installed on the top plate, which is used for adjusting the height of the demolding mechanism and the mold and for vibration; the driving mechanism is interconnected with the demolding mechanism, which is used for clamping and limiting the mold and for vibrating the workpiece during demolding.

[0005] Preferably, the lifting mechanism includes a first cylinder symmetrically fixed on the base, and the output end of the first cylinder is fixed to a base plate. The base plate and the slide rod are slidably connected. The slide rod is symmetrically fixed on the lower end face of the support plate. The support plate is located below the conveying roller, and a first spring is fixed between the support plate and the base plate. The height of the base plate and the support plate can be adjusted by the first cylinder, thereby providing a basic guarantee for lifting the mold and ensuring the normal operation of the device. The sliding guide effect between the base plate and the slide rod can ensure the stability of the support plate when moving relative to the base plate.

[0006] Preferably, the pallet is connected to several rollers with equally spaced bearings, and the upper end face of the rollers is lower than the upper end face of the conveying rollers. The rollers and the conveying rollers are vertically distributed. The rollers are set between two adjacent conveying rollers. By limiting the height of the rollers, it can be ensured that the rollers will not interfere with the movement of the mold or concrete workpiece when the conveying rollers are conveying it, thus ensuring the normal operation of the device. Furthermore, the rolling action of the rollers facilitates the normal demolding process.

[0007] Preferably, the driving mechanism includes a second motor fixed to the upper end of the top plate, and a threaded rod is fixed to the output end of the second motor. The threaded rod is connected to the lower end face of the top plate by a bearing, and a limit plate is fixed to the lower end face of the threaded rod. The threaded rod and the bracket are threadedly connected, and the bracket is fixedly connected to the movable frame. The second motor drives the threaded rod to rotate, thereby allowing the bracket and the movable frame to move up and down, thus providing a basic guarantee for the subsequent separation of the mold and the concrete workpiece.

[0008] Preferably, the movable frame is fixed with an ear plate on its side, and the ear plate is slidably connected to the support rod. The ear plate and the support rod are distributed in a one-to-one correspondence. During the up-and-down movement of the movable frame, the sliding guidance between the ear plate and the support rod can ensure the stability of the device's movement.

[0009] Preferably, the threaded rod and the square rod are slidably connected, and a disc is fixed to the lower end face of the square rod. A pulley with an I-shaped cross-section is connected to the lower end face of the disc via a bearing. At the same time, the pulley and the sliding rod are slidably connected. Through the sliding action between the square rod and the threaded rod, the position of the disc and the pulley relative to the sliding rod can be kept unchanged, thus providing a basic guarantee for the normal operation of the device. Furthermore, through the rotation of the disc and the pulley with the threaded rod, combined with the rolling action between the pulley and the sliding rod, a basic guarantee can be provided for the left and right reciprocating movement of the sliding rod.

[0010] Preferably, the slide bar is also symmetrically fixed with crossbars on both sides, and the crossbars are slidably connected to the movable frame. A second spring is also fixed between the crossbars and the movable frame. At the same time, the crossbars are fixed to the fixed plate. The fixed plate is located on the outside of the movable frame and is equipped with a demolding mechanism. When the slide bar moves back and forth relative to the movable frame, the sliding guide between the crossbars and the movable frame can ensure the stability of the slide bar's movement. The second spring can also provide a buffering effect, ensuring the stability of the device's operation.

[0011] Preferably, the demolding mechanism includes a second cylinder fixed to the fixed plate, and the output end of the second cylinder is fixed with a mounting frame, and the mounting frame is fixed with a clamping plate. The second cylinder can extend and retract to move the mounting frame and the clamping plate, thereby adjusting the distance between the left and right clamping plates so as to clamp concrete molds of different sizes and provide a basic guarantee for the subsequent demolding of concrete workpieces.

[0012] Preferably, the mounting frame has a movable plate on its side, and several metal balls are fixed at equal intervals on one side of the movable plate, with the end faces of the metal balls flush with the clamping surface of the clamping plate. A third spring is fixed between the movable plate and the mounting frame. Fixed rods are symmetrically fixed on the other side of the movable plate, and the fixed rods are slidably connected to the mounting frame. A round shaft is also connected to the fixed rod with a bearing. Through the sliding action between the fixed rod and the mounting frame, the movable plate and the metal balls can move relative to the mounting frame. By restricting the end faces of the metal balls from the clamping surface of the clamping plate, the device can automatically adapt to molds of different sizes for demolding operations. Furthermore, the action of the metal balls provides a basic guarantee for the impact of the mold, thus providing a basic guarantee for the vibration demolding of concrete workpieces.

[0013] Preferably, a vertical plate is provided on the side of the circular shaft, and arc-shaped protrusions are fixed on the vertical plate at equal intervals. The circular shaft and the arc-shaped protrusions are in contact to form a rolling connection. A guide rail is also fixed on the vertical plate, and the guide rail is slidably connected to the mounting frame. A slider is fixed at the upper end of the vertical plate, and the slider is slidably connected to the guide rod. The guide rod is symmetrically fixed to the lower end face of the top plate. Through the sliding action between the slider and the guide rod, the position between the vertical plate and the mounting frame can be kept unchanged, which facilitates demolding operations for molds of different sizes. Furthermore, through the contact separation action between the circular shaft and the arc-shaped protrusions and the elastic action of the third spring, a basic force can be provided for the movement and reset of the metal ball, ensuring the normal operation of the device.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This demolding device for concrete preparation uses a first motor to drive the conveying rollers to rotate synchronously. In conjunction with the roller feeding conveyor and roller unloading conveyor, it realizes the automated conveying of molds and concrete workpieces without the need for manual transfer. The coordinated work of the lifting mechanism, driving mechanism and demolding mechanism realizes the fully automated operation of mold positioning, clamping, lifting, vibration demolding and resetting. It completely replaces the tedious manual prying, knocking and transfer processes, greatly reduces the labor intensity of operators, and significantly improves the demolding efficiency, which is suitable for the needs of large-scale concrete component production. 2. The demolding device for concrete preparation drives the demolding mechanism and mold to perform orderly left and right reciprocating motions through the drive mechanism, simulating the shaking action during manual demolding, which initially breaks the adhesion between the concrete and the mold. At the same time, the metal ball in the demolding mechanism, with the cooperation of the third spring and the arc-shaped protrusion, intermittently knocks on the mold, further breaking the adhesion surface. The two methods work together to effectively solve the problems of incomplete demolding and workpiece jamming in existing devices, ensuring that the concrete workpiece is smoothly separated from the mold. 3. The demolding device for concrete preparation, through the buffering effect of the first spring in the lifting mechanism, can achieve a smooth drop of the concrete workpiece when it is demolded and separated, avoiding collision damage caused by the direct drop of the workpiece. The rollers on the support plate contact the mold and the workpiece to roll, which not only ensures the smooth movement of the workpiece, but also reduces friction damage on the surface of the workpiece, significantly improving the demolding quality of the concrete workpiece. 4. The demolding device for concrete preparation has a clamping plate in the demolding mechanism for clamping and fixing the mold. The metal ball on the movable plate contacts the mold. During the knocking and vibration process, the elastic contact of the metal ball can avoid hard impact on the mold surface and reduce mold wear. At the same time, the precise control of the drive mechanism and the lifting mechanism ensures that the mold is subjected to uniform force during demolding, avoiding mold deformation caused by force deviation. In addition, during the device reset process, the mold will still swing back and forth and be knocked and vibrated, which can promote the dissipation of residual concrete debris in the mold, reduce the corrosion and wear of the debris on the mold, extend the service life of the mold, and reduce production costs.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-7 This invention provides a technical solution: a demolding device for concrete preparation, comprising a base 1, a first motor 2 fixed on the base 1, a conveying roller 3 fixed at the output end of the first motor 2, the conveying roller 3 being connected to the base 1 with equally spaced bearings, and adjacent conveying rollers 3 being synchronously rotated through pulleys and belts, a lifting mechanism 4 installed on the base 1, and the lifting mechanism 4 being used for supporting and adjusting the mold, a support rod 5 fixed on the base 1, a top plate 6 fixed at the upper end of the support rod 5, a driving mechanism 7 installed on the top plate 6, and the driving mechanism 7 being used to realize the height adjustment and vibration of the demolding mechanism 8 and the mold, the driving mechanism 7 being interconnected with the demolding mechanism 8, and the demolding mechanism 8 being used to realize the clamping and limiting of the mold and the vibration demolding of the workpiece.

[0019] The lifting mechanism 4 includes a first cylinder 401 symmetrically fixed on the base 1, and a base plate 402 is fixed to the output end of the first cylinder 401. The base plate 402 is slidably connected to the slide rod 403. The slide rod 403 is symmetrically fixed to the lower end face of the support plate 404. The support plate 404 is located below the conveyor roller 3, and a first spring 405 is fixed between the support plate 404 and the base plate 402. Several rollers 406 are connected to the support plate 404 with bearings at equal intervals. The upper end face of the rollers 406 is lower than the upper end face of the conveyor roller 3, and the rollers 406 are vertically distributed with the conveyor roller 3. The rollers 406 are arranged between two adjacent conveyor rollers 3. When using a release maker for concrete preparation, such as Figures 1-7 As shown, the entire device is first positioned between the roller feeding conveyor and the roller unloading conveyor. A steel mold with the concrete workpiece to be demolded is placed face down on the roller feeding conveyor, which then transports the mold. When the mold contacts the conveyor roller 3, the first motor 2 drives the conveyor roller 3 to rotate. Combined with the synchronous transmission of the pulley and belt, multiple conveyor rollers 3 rotate synchronously, moving the steel mold directly above the lifting mechanism 4 (this movement can be monitored using a visual inspection mechanism to ensure the mold's position). At this point, the first motor 2 stops working. By controlling the extension of the first cylinder 401, the base plate 402, support plate 404, and roller 406 are lifted by force. When the roller 406 contacts the steel mold, the first... As cylinder 401 continues to extend, the weight of the steel mold and the internal concrete workpiece causes the position of the support plate 404 and roller 406 to remain stationary relative to the position of the steel mold. Meanwhile, the base plate 402 moves relative to the support plate 404. This movement, combined with the sliding guide between the base plate 402 and the slide rod 403, ensures the stability of the base plate 402's movement. At this point, the first spring 405 contracts under pressure. When the elastic force of the first spring 405 equals the weight of the steel mold and the internal concrete workpiece, the continued extension of cylinder 401 allows the base plate 402, support plate 404, roller 406, steel mold, and internal concrete workpiece to move upwards again until the steel mold aligns with the demolding mechanism 8. The demolding mechanism 8 includes a second cylinder 801 fixed to a fixed plate 713, and a mounting bracket 802 is fixed to the output end of the second cylinder 801. A clamping plate 803 is fixed on the mounting bracket 802. A movable plate 804 is provided on the side of the mounting bracket 802, and a plurality of metal balls 805 are fixed at equal intervals on one side of the movable plate 804. The end faces of the metal balls 805 are flush with the clamping surfaces of the clamping plate 803. A third spring 806 is fixed between the movable plate 804 and the mounting bracket 802. A fixing rod 807 is symmetrically fixed to the other side of the movable plate 804. The fixed rod 807 is slidably connected to the mounting bracket 802, and a round shaft 808 is also connected to the fixed rod 807 by a bearing; a vertical plate 809 is provided on the side of the round shaft 808, and arc-shaped protrusions 810 are fixed at equal intervals on the vertical plate 809, and the round shaft 808 and the arc-shaped protrusions 810 are in contact to form a rolling connection; a guide rail 811 is also fixed on the vertical plate 809, and the guide rail 811 is slidably connected to the mounting bracket 802; a slider 812 is fixed at the upper end of the vertical plate 809, and the slider 812 is slidably connected to the guide rod 813; and the guide rod 813 is symmetrically fixed to the lower end face of the top plate 6. After the lifting mechanism has lifted the four pairs of steel molds and the internal concrete workpieces, as follows: Figures 1-7 As shown, by controlling the extension of the second cylinder 801, the mounting bracket 802 and the clamping plate 803 can be moved, thereby reducing the distance between the two clamping plates 803 until the clamping plates 803 contact the steel mold to clamp and fix the steel mold. When the mounting bracket 802 moves, the movable plate 804, the metal ball 805 and the vertical plate 809 are moved simultaneously. When the clamping plate 803 contacts the steel mold to clamp and fix it, the metal ball 805 is in contact with the steel mold. The vertical plate 809 moves, and the sliding guide between the slider 812 and the guide rod 813 can ensure the stability of the movement of the vertical plate 809. The drive mechanism 7 includes a second motor 701 fixed to the upper end of the top plate 6, and a threaded rod 702 fixed to the output end of the second motor 701. The threaded rod 702 is bearing-connected to the lower end face of the top plate 6, and a limit plate 703 is fixed to the lower end face of the threaded rod 702. The threaded rod 702 is threadedly connected to the bracket 704, and the bracket 704 is fixedly connected to the movable frame 705. Ear plates 706 are fixed to the side of the movable frame 705, and the ear plates 706 are slidably connected to the support rod 5. The ear plates 706 and the support rod 5 are distributed in a one-to-one correspondence. The threaded rod 702 and the square rod 707... The connection between the square rod 707 and the movable frame 705 is slidable. A disc 708 is fixed to the lower end of the square rod 707, and a pulley 709 with an I-shaped cross section is connected to the lower end of the disc 708. The pulley 709 and the sliding rod 710 are rolled together. A crossbar 711 is symmetrically fixed on the sliding rod 710. The crossbar 711 and the movable frame 705 are slidably connected. A second spring 712 is fixed between the crossbar 711 and the movable frame 705. The crossbar 711 and the fixed plate 713 are fixed to each other. The fixed plate 713 is located on the outside of the movable frame 705, and a demolding mechanism 8 is installed on the fixed plate 713. After the steel mold is clamped and fixed, as follows Figures 1-7 As shown, the second motor 701 drives the threaded rod 702 to rotate forward. With the threaded connection between the threaded rod 702 and the bracket 704, the movable frame 705 moves upward at a uniform speed under force. With the sliding guide between the ear plate 706 and the support rod 5, the stability of the upward movement of the movable frame 705 can be ensured. Since the steel mold and the concrete workpiece are in an adhered state at this time, the upward movement of the movable frame 705 can synchronously drive the clamping plate 803 and the steel mold to move upward at a uniform speed. This reduces the gravity of the steel mold and the concrete workpiece on the roller 406. With the elastic effect of the first spring 405, the support plate 404 and the roller 406 can move upward with the steel mold and the concrete workpiece, ensuring that the roller 406 is always in contact with the lower end face of the steel mold and the concrete workpiece, thereby realizing the follow-up adjustment function of the roller 406. When the threaded rod 702 rotates, causing the movable frame 705 to move upward, it simultaneously drives the crossbar 711 and the sliding rod 710 to move upward. Due to the nested fit between the I-shaped pulley 709 and the sliding rod 710, the pulley 709 moves synchronously with the upward movement of the sliding rod 710, thereby driving the disc 708 upward. Combined with the sliding guide effect between the square rod 707 and the threaded rod 702, the stability of the disc 708's movement can be ensured. Furthermore, when the threaded rod 702 rotates, it simultaneously drives the disc 708 and the pulley 709 to rotate. Through the rolling action between the pulley 709 and the sliding rod 710, the sliding rod 708... 10 performs orderly left-right reciprocating motion, which, in conjunction with the sliding action between the square rod 707 and the movable frame 705, ensures the stability of the movement of the slide bar 710. Furthermore, through the left-right reciprocating motion of the slide bar 710, the fixed plate 713, the second cylinder 801, the mounting frame 802, the clamping plate 803, the steel mold, and the concrete workpiece can be driven to perform orderly left-right reciprocating motion simultaneously. At this time, the roller 406 contacts and rolls with the steel mold and the concrete workpiece. Through the left-right reciprocating shaking of the steel mold and the concrete workpiece, the shaking of the mold during manual demolding can be simulated to improve the demolding effect of the concrete workpiece. When the movable frame 705 moves upward, it simultaneously drives the mounting frame 802, clamping plate 803, movable plate 804, metal ball 805, round shaft 808, steel mold, and concrete workpiece to move upward. This, combined with the sliding guide action between the mounting frame 802 and the guide rail 811, ensures the stability of the mounting frame 802's movement. Furthermore, during the upward movement of the mounting frame 802, clamping plate 803, movable plate 804, metal ball 805, round shaft 808, steel mold, and concrete workpiece, when the round shaft 808 contacts and rolls against the arc-shaped protrusion 810, the round shaft 808 is subjected to force and moves, thereby simultaneously driving the fixed rod 807, movable plate 804, and metal ball 805 away from the steel mold. With the sliding guide action between the fixed rod 807 and the mounting bracket 802, the stability of the movement of the movable plate 804 and the metal ball 805 can be ensured. When the third spring 806 is compressed under force, and the round shaft 808 separates from the arc-shaped protrusion 810, the movable plate 804 and the metal ball 805 are reset under the elastic action of the third spring 806. The metal ball 805 impacts the steel mold upon reset, causing the steel mold to vibrate, thereby effectively breaking the adhesion between the steel mold and the concrete workpiece. In summary, through the reciprocating upward movement of the steel mold and the impact vibration, the concrete workpiece can be separated from the steel mold, thereby achieving the demolding effect of the concrete workpiece. Furthermore, when the concrete workpiece separates from the steel mold, the roller 406 remains in contact with the lower end face of the concrete workpiece. The separation of the concrete workpiece from the steel mold exerts a force on the roller 406, causing it to move downwards under the weight of the concrete workpiece. Combined with the action of the first spring 405, this provides a buffer during demolding, preventing the concrete workpiece from falling directly and causing collision damage, thus ensuring the demolding quality of the concrete workpiece. After demolding, the first cylinder 401 retracts, causing the roller 406 to move downwards and reset until the concrete workpiece contacts the conveyor roller 3. Once the roller 406 has reset, its upper end face is lower than the upper end face of the conveyor roller 3, preventing the conveyor roller 3 from interfering with the movement of the concrete workpiece when conveying it to the roller unloading conveyor. After the concrete workpiece is moved to the roller unloading conveyor, the first cylinder 401 extends again, causing the roller 406 to contact the steel mold. At this time, the second motor 701 drives the threaded rod 702 to reverse, which can reset the movable frame 705. During the reset process, the steel mold will continue to swing left and right and vibrate, which facilitates the removal of residual concrete debris inside the steel mold for subsequent processing. After the movable frame 705 is reset, the second cylinder 801 retracts to release the clamping limit of the steel mold, and the first cylinder 401 retracts again, placing the steel mold on the conveying roller 3 for unloading.
